  1. 1. Enzyme substrate solvent interactions : a case study on serine hydrolases

    Författare :Linda Fransson; Karl Hult; Jürgen Pleiss; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipase; esterase; specificity; Bioengineering; Bioteknik;

    Sammanfattning : Reaction rates and selectivities were measured for transacylation of fatty acid esters in solvents catalysed by Candida antarctica lipase B and by cutinase from Humicola insolens. With these enzymes classical water-based enzymology can be expanded to many different solvents allowing large variations in interaction energies between the enzymes, the substrates and the surrounding.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molecular recognition; interactions; phage display; biomolecular interactions; phage; adenine; influenza virus replication; oseltamivir; imprinted polymers.;

    Sammanfattning : The focus of this thesis has been to examine two new concepts involving the interaction of biological agents with synthetic material surfaces.The feasibility of deploying phage display techniques for the screening of materials in non-biological media was examined in two studies.

    Sammanfattning : A considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. LÄS MER

  7. 5. Exploring Molecular Interactions : Synthesis and Studies of Clip-Shaped Molecular Hosts

    Nyckelord :Organic chemistry; Glycoluril clips; host-guest systems; supramolecular chemistry; complexation induced shifts; conformational restriction; NMR spectroscopy; fullerene binding; Organisk kemi;

    Sammanfattning : Molecular recognition via noncovalent interactions plays a key role in many biological processes such as antigen-antibody interactions, protein folding, the bonding and catalytic transformation of substrates by enzymes, etc. Amongst these noncovalent interactions, electrostatic interactions, hydrogen bonding, π-π interactions, and metal-to-ligand bonding are the most prominent.
